Applet Canvas TextField actionPerformed()

[asiavoices]

Hello all,

I have a peculiar problem with my applet in that my applet does not seem to accept a value in a TextField.

Background:

1. My application is a Blackjack game.

2. The TextField in question :-( is the one I use to have people enter the dollar amount of their bet.

3. There are other buttons (Deal, Stand, Shuffle and New Game) which all work accordingly.

Question:

1. What am I doing wrong in not having my program recognize or accept values in the TextField? Remember... everything works but now I want to have the ability to have users enter an amount to bet.


Here's a snippet of my code:

/* ==================================

================================== */

import java.awt.*;
import java.awt.Image;
import java.awt.event.*;
import java.applet.*;



public class Blackjack extends Applet
{
Button hit;
Button stand;
Button shuffleDeck;
Button newGame;

BJCanvas board;
Panel buttonPanel;

Label bankLabel;
Label displayBank;
Label betLabel;

TextField betField; <--- the problem!

private double betEntered = 0.00d;

public void init()
{
/*------ the labels -----------*/

bankLabel = new Label(&quot;Bank:&quot;
displayBank = new Label(&quot;500.00&quot;
betLabel = new Label(&quot;You Bet:&quot;

betField = new TextField(8);

/*------ the Buttons -------*/
hit = new Button(&quot;Deal!&quot;
stand = new Button(&quot;Stand Pat&quot;
shuffleDeck = new Button(&quot;Shuffle&quot;
newGame = new Button(&quot;New Game&quot;


setBackground( new Color(0,50,40) );
setLayout( new BorderLayout(3,3) );

Panel buttonPanel = new Panel();
buttonPanel.setBackground( new Color(220,200,180) );
buttonPanel.setLayout( new GridLayout(1,8) );
add(buttonPanel, BorderLayout.NORTH);


/* --- my own canvas BJCanvas ---*/

BJCanvas board = new BJCanvas();
add(board, BorderLayout.CENTER);


buttonPanel.add(bankLabel);
buttonPanel.add(displayBank);
buttonPanel.add(betLabel);

betField.addActionListener(board);
buttonPanel.add(betField);

hit.addActionListener(board);
buttonPanel.add(hit);

stand.addActionListener(board);
buttonPanel.add(stand);

shuffleDeck.addActionListener(board);
buttonPanel.add(shuffleDeck);

newGame.addActionListener(board);
buttonPanel.add(newGame);

} // end init()

............

class BJCanvas extends Canvas implements ActionListener
{

Deck deck;
BlackjackHand dealerHand;
BlackjackHand playerHand;

String message;
boolean gameInProgress;
Font bigFont;
Font smallFont;

/* ------ my Constructor. Creates fonts and starts the first game. -------------*/

BJCanvas()
{
setBackground(new Color(255,204,102));
smallFont = new Font(&quot;Verdana&quot;, Font.PLAIN, 11);
bigFont = new Font(&quot;Verdana&quot;, Font.BOLD, 13);
doNewGame();
} // end of my constructor

/*---- actionPerformed() method -----

public void actionPerformed(ActionEvent buttonEvent)
{
Object buttonClicked = buttonEvent.getSource();

//If the HIT button was clicked

if (buttonClicked == hit)
{
doHit();
}
else if (buttonClicked == stand)
{
doStand();
}

else if (buttonClicked == shuffleDeck)
{
deck.shuffle();
message = &quot;Shuffle Complete...&quot;;
repaint();
}

else if (buttonClicked == newGame)
{
doNewGame();
}

} // end of actionPerformed()


.................

/* -----------------------------
doHit() method()

This method is called when the user clicks the &quot;Hit!&quot; button. I want to display the text entered to see if it does work! :-(
----------------------------- */


void doHit()
{
double betEntered = (Double.parseDouble(betField.getText().trim()));
displayBank.setText(Double.toString(betEntered));
...

} // end of doHit() method

} // end nested class BJCanvas



} // End of Blackjack applet


any ideas?

Thank you,

Hello again all,

Unfortunately, I still have not solved my problem.

I've tried annonymous inner classes and still with no success.

Any ideas?

Thank you,

Christopher
